I have read where people put macroalgae in their refugium to clean up the water and get rid of bad algae. I don't have a refugium but was wondering if I could put this in my tank? I understand some fish like to eat it too. I have seen some red and some green macroalgae. Is one better than the other? Do they float in the water or should you attach them to a rock? Thanks for your help.
